About Pream

Dear Sir:
In the open software, the function Pream

when resync on the first subframe, TOW matches clock to 300 seconds; resync=
 on the other subframes, TOW matches clock to 3 seconds.

I don't know why? why should be 3 seconds when resync on the other subframe=
s? Is 300 seconds Ok?

Best Regards!
Looking forward for your letter!

                                                                    Yours

message frame is reached and during the time taken to decode the nav messag=
e means a few bits may overwrite the previous set.  With the data overflow =
array we won't miss this data and it can be used later without any problems.

> This is due to the bookkeeping of data bits which is handled in two place=
s.  The chan[ch].meas_bit_time is the data bit into the week the measuremen=
t was made.  It is unambiguous but since it is on the user side of the inte=
rface it could be off by 1 bit.  The other value "bit" comes from the data =
bit counter in the GP2021 and is accurate but ambiguous since it only count=
s up to 50 data bits and then rolls over.  This part of the code resolves t=
he ambiguity and corrects the meas_bit_time for later construction of the p=
